The man arrested after attempting to upstage Adele at the Grammys says his stunt was spontaneous and he hopes it doesn't hurt his chances to remain in Los Angeles.

Ukraninan television journalist Vitalii Sediuk says he accepts responsibility for entering the show without a ticket, but that he hopes the incident has exposed some security lapses.

The 24-year-old was arrested after briefly taking the microphone before Adele accepted her Grammy on the show's telecast.

He was shooed away by presenter Jennifer Lopez and later released by police.

Jail records show Sediuk spent the next several hours in custody and was ordered to appear for a March 4 court date.

He told The Hollywood Reporter, which first reported his arrest, that he did not have a ticket to the show and took musician Adam Levine's seat before going on stage.

Sediuk's intrusion came after Los Angeles police increased security at the Grammys due to an ongoing manhunt for a rogue ex-officer targeting police and their families.

Publicists for the Grammy Awards did not return emails seeking comment on the incident.

Sediuk, 24, has gained notoriety for other stunts involving celebrities. Will Smith slapped the 24-year-old last year after attempting to kiss him on the red carpet of the Moscow premiere of ''Men in Black III.''

Madonna received a bouquet of hydrangeas from Sediuk at the 2011 Venice Film Festival and promptly stashed them under a table, declaring, ''I absolutely loathe hydrangeas.''
